5.2 Master Clock
The ZL30108 can use either a clock or crystal as the master timing source. Zarlink Application Note ZLAN-68 lists a
number of applicable oscillators and crystals that can be used with the ZL30108.
5.2.1 Clock Oscillator
When selecting a Clock Oscillator, numerous parameters must be considered. These includes absolute frequency,
frequency change over temperature, output rise and fall times, output levels, duty cycle and phase noise.
The output clock should be connected directly (not AC coupled) to the OSCi input of the ZL30108 and the OSCo
output should be left open as shown in Figure 11.
